| 摘 要： | 为进一步研究煤体爆破作用机理,提高瓦斯抽放效果,从理论上将煤体爆破损伤断裂分为爆炸波作用的初始阶段和爆生气体与瓦斯气体作用的后期阶段,并确定了两个阶段的断裂损伤准则.根据相似理论设计了煤体爆破损伤规律模拟试验,测试了试块超声波波速(计算损伤参量)和爆炸应变波,试验结果表明,模拟煤体爆破损伤是爆炸冲击波、爆炸应力波、爆生... |

| Abstract: | In order to further study the coal blasting mechanism and improve the gas drainage effect in coal mine,we analyzed the process of coal blasting damage and fracture and divided it into the initial stage of blast waves and the later stage of the detonation gas and coal mine gas,then we selected the damage and fracture criterion.Based on the similarity theory,we designed coal blast experiment and measured ultrasonic wave velocity and blast strain waves.The results show that the coal blast damage is the result ... |
